Your suggestion. One colour for months that beat the target of 100, another for those that miss. The eye sorts the year before it reads a single number.
02Labelled line
The plainest version. Bars stay one colour and the line carries a badge saying what it is, so nobody has to ask what the dashes mean.
03Tolerance band
A band instead of a line, here 100 ± 8. Inside the band is "on plan", so only the real exceptions take a colour.
04Two lines: target and average
The target is the promise, the average is what actually happened. The gap between the two lines is the story.
05Variance from the line
Drop the bars and plot only the gap. The line becomes the zero axis, which makes small misses visible at a glance.
06Bullet chart
Shaded bands for poor, fair and good, with a target tick. Four KPIs fit where one gauge would have gone.
07Shaded above and below
On a line chart, fill the area between the line and the target in two colours. Surplus and shortfall read as areas, not points.
08Several benchmarks
Budget, last year and the industry figure together. Label each line at its right end rather than in a legend.
09Pace line
For anything cumulative the reference is a ramp, not a flat line. The shading shows whether you are ahead of pace or behind it.
10Draggable threshold
Drag the line to ask "what if the target were higher?". The colours and the count follow it.
